Application November 18, 1931, Serial No. 575,979 In Germany November22, 1930 3 Claims.

This invention relates to high tension distributors for the ignitionsystems of internal combustion engines. In distributors of this kind ashitherto known the distributor segments are I moulded in the distributorbody made of insulating material.- Such designs have the disadvantagesthat the whole high tension distributor has to be replaced after theends of the distributor segments have been used up under the influenceof the high tension current passing from these segments unto theelectrodes in the distributor blocks. Apart from this, the segments aremoulded under pressure into the insulating material of this distributor,thereby being deformed to a certain extent making the condition of theinsulating material worse.

According to the present invention, these disadvantages are overcome bythe distributor segment being arranged interchangeably on the outside ofthe distributor body and the distributor body, made of insulatingmaterial, being moulded by itself without any metal segments inside.

Referring to the drawing Fig. 1 is a vertical section through the high atension distributor device, and

Fig. 2 a vertical section turned through 90 with respect to Fig. 1.

Fig. 3 is a plan view of the distributor.

The preferred form of the device is the only an embodiment of theinvention illustrated and will now be described in detail, but withoutimplication of limitation beyond the scope of the invention as set forthin the claims.

a is the distributor body made of insulating :5 material, 12 thefastening flange of same for fixing the distributor body on the largedistributor gear, not shown in the drawing, and c is a boss arranged inthe axis d--e at the end of the body a. 1 represents the distributorsegment mounted on the outside of the distributor body. Fig. 1 shows howthe end g of this segment is fixed to the fastening flange b by means ofthe screw it and the insert 1' the latter being cast integrally with thedistributor body. Fig. 2 shows in the same way the other end of thedistributor segment which is turned through 90 with regard to the end gof the segment; it is fixed to the support I of the distributor body bymeans of the screw h and the insert 1, the latter being again cast intothe insulating material. The boss c of the distributor body has anopening m (see Fig. 1) and an opening n (see Fig. 2) in which thedistributor segment is guided thereby preventing the same from turning.To the distributor segment I is riveted a metal bushing o in the axialhole of which the high tension carbon brush is housed; the carbon brushis not shown on the drawing. Said carbon brush transmits the hightension current to the distributor segment 7; the current passes acrossthe air gap p (see Fig. l) and after the distributor has turned through90, across the air gap 11 (see Fig. 2) to the electrodes 1* and srespectively.

After the ends g and is of the distributor segment have been used upunder the influence of the high tension current, the distributor segment,1 can be taken oif by loosening both screws h and the old segment cannow be replaced by a new one, but the distributor body itself can beused over again. On the other hand it is quite clear that an insulatingbody moulded by itself without any metal strips inside will give thebest guarantee for an excellent insulating quality.

What I claim is:

1. In a high tension distributor for magneto electric ignition systemsof internal combustion engines the combination of a distributor body ofconical shape, having at one end a fastening flange for fixing thedistributor body to the large distributor gear, a distributor segment ofsame shape as the distributor body in its vertical sec tion, fixingmeans for said distributor segment and metal inserts for said fixingmeans cast into the insulating material of said distributor body.

2. In a high tension distributor body for magneto electric ignitionsystems of internal combustion engines the combination of a distributorbody of conical shape having at one end a fastening flange for fixingthe distributor body to the large distributor gear, a distributorsegment of same shape as the distributor body in its vertical section,one end of said distributor segment being fixed to said fastening flangeof the distributor, the other end being fixed to an arm of thedistributor body situated remote from said fastening flange, both endsbent aproximately 90 from the main portion, fixing screws for saiddistributor segment and fixing inserts for said fixing screws cast intothe insulating material of said distributor body.

3. In a high tension distributor body for magneto electric ignitionsystems of internal combustion engines the combination of a distributorbody of conical shape having at one end a fastening flange for fixingthe distributor body to the large distributor gear, a distributorsegment of same shape as the distributor body in its vertical section,one end of said distributor segment being fixed to said fastening flangeof the distributor, the other end being fixed to an arm of the disbutlocated in its axis having two slots for guiding the distributorsegments, thereby preventing the latter from turning and having acentral hole to house a metal bushing, which is fixed to the distributorsegment, this bushing containing the high tension carbon brush.

GOTTLIEB STEINER.
